. tures of said machine.

I have shown my invention, in the present instance, embodied in a No;Remington machine, in which the invention may be readily incorporatedrially modifyingthe existing structural fea- It should be understood,however, that the invention is not restricted to use in said machine butmay be employed in typeWrit-ing and like machines generall whereverfound available.

The filling in of addresses on letter sheets having the body of theletter previously printed, is laborious and time consuming when the workis to be carefully matched as to line spacing and marginal alignment, aswell as to denseness of imprints, and re quires considerable skill tothus accurately and neatly fill in the addresses, and as nearly aspossible have each letter present the appearance of a wholly typewrittenletter. So much so is this the case that only the more slrilfuloperators can be relied upon to effectively do this work, and they arepaid a higher rate per iilled in, for their more perfectly matched work,as it necessarily requires more time. By the present invention means areprovided that enable even an inexperienced operator to rapidly fill inthe addresses in such work and with mechanical accuracy position eachaddress with reference to the previously printed body of the letter bothin spacing of the lines added and a marginal alignment of such lines.

The carriage of a No. 50 Remington machine comprises end plates 1connected by united carriage rails 2 and a cross rod 3., A cylindricalplaten 4 is revolubly mounted in bearing members carried by the endplates 1;

each end of the platenshaft having a finger Wheel 5 detachablyfixedthereto. The usual paper fingers 6, one of which is shown in Fig. 1, aremounted for sliding adjustment along the connecting rod 3. A linespacing ratchet wheel 7 may be connected by the usual clutch (not.shown) to turn with the platen. Said clutch is controlled by the usualfinger piece 8, except that in the present instance said finger piece isreturned to normal position by a spring 9 to close the clutch.

without modifying or mate- 7 thousand of addresses The platen isadvanced line-by-line by the usual or any suitable line spacing pawl a,controlled by a finger piece I) which is also effective at the same timeto return the carriage to the right. I

A paper table 10 is mounted by suitable means (not shown) in the rear ofthe platen to feed work sheets to the bight between the usual paper feedrollers (not shown) and the platen at the introductory side of theplaten. The paper table is slotted horizontal- 1y at 11 to receivetherethrough the stems of screws 12. The head of each screw is secured,by solder or otherwise, to a metallic strip 13. At the rear of the papertable each screw receive's a thumb nut 14 (see Fig. 2), the reducedshouldered end of which bears against a washer 15, which in turn bearsagainst the rear side of the paper table. The stem of each screw 1 alsopasses freely through an ap erture in the foot piece 16 of a side edgeguide 17, the foot piece resting on the front face of the paper tableand the long side edge guide proper 17 extending up in a plane atsubstantially right angles to the plane of the table. There arepreferably two of these guides, one coacting witheach edge of a worksheet. By loosening the nuts l the guides may be ad justed towards oraway from each other, and a tightening of the nuts will firmly clamp andhold the guides in their adjusted positions.

The carriage is power driven and advanced step-by-step in itsletterspace movements under control of the usual carriage escapeinentmechanism which includes feed racl: 18 releasably engaged with the usualfeed pinion 0. Instead, however, of merely pivoting this feed rack onthe carriage in the usual manner, I prefer to mount it so as to affordin addition a relative sliding movement between the carriage and saidfeed raclr, as will more clearly appear irom a consideration of Fig. 3.At the ends of the feed rack are secured by screws 19 two brackets 20and 21. A pivot pin 22 is mounted to turn and receive a sliding movementin a bushing 23 threaded into a tapped opening in the right hand endplate 1 of the carriage, and held in position thereon by a lock nut 24.The inner end of the pin 22 is fixed to and constitutes a support forthe bracket 20, so as to provide a pivotal and sliding support for oneend of the feed rack 18. The bracket 21 also is fixedly secured to apivot pin 25 that is supported for sliding as well as for pivotalmovement in a bushing 28 threaded into a tapped opening in the left handen plate 1 of the carriage. his bushing held in its adjusted position bya lock nut 27. An arm 28 is fixed to the outer endof the pin 25 andextends upward and forward therefrom and terminates in a finger piece29. A depression of the finger piece is effective to turn the rack withits supporting pivot pinsland release the rack from the feed pinion 0.This construction is much the same as that usually employed, except thatordinarily the bushings 23 and 26 are screwed in to prevent any relativemovement between the feed rack and the carriage lengthwise of the rack.In accordance with the present invention, I prefer to employ a coiledexpansion spring 30 surrounding the pin 25 and bearing at one endagainst a washer 31 carried by the reduced end of the bushing 26. Theother end of the spring bears against the bracket 21, or against aflanged part of the pin 25 connected to said bracket. A sleeve or collar32 loosely surrounds the pivot pin 22 and has an up wardly extending arm33 fixed thereto. The inner end of this sleeve constitutes an abut mentagainst which the bracket 20 bears under the force'of the spring 30. Aheaded shouldered pivot screw 34 is seated loosely in an opening in thearm 33 and is received at its threaded end in a tapped opening in theinner end. of a adjusting screw 35. By this connection the screw 35 isfree to turn relatively to the arm 33 but the two are connected againsrelative movement longitudinally of the platen. The screw 35 extendswith its axis parallel to the axis of the platen through a tappedopening in the right hand end plate 1 and is provided at its outer endwith a knurled head 36, thus constituting a thumb screw. Thisconstruction provides a micrometer adjusting means by which the carriageas a whole, with the platen carried thereby, may be adjusted relativelyto the feed rack in the direction of the axis of the platen, either toright or left, depending on the direction in which the screw 35 isturned. If the screw 35 be turned clockwise the carriage, and the platencarried thereby, will be moved to the left relatively to the feed rackas the latter is held engaged with the feed pinion 0. On the other hand,if the screw be adjusted in the reverse directi on the carriage andplaten will be adjusted to the right. However, under all adjustments,the fee d rack and carriage travel together in the ordinary operation ofthe machine. It will be understood that this adjustment cf the carriageand platen need not be in excess of any desired fraction of a singleletter space dis tance. and is intended to provide for perfect marginalalignment between the previously printed body portion of the letter andthe address to be filled in on the typewriter without the necessity anddifiiculty of effecting a minute lateral adjustment of the paper and theside edge guides to effect such alignment. The marginal alignment of theletters referred to is indicated by the dot and dash line in Fig. 1which will be hereinafter referred to more in detail.

The means for rapidly and accurately positioning the paper to receivethe first line of the address will now be described.

In order that the platen may be accurately aligned in the carriage, theN0. 50 Remington machine is provided with bearings for the platen shaftthat are mounted for fore and aft adjustment-on the end plates 1. in thepresent instance the left-hand bearing is cur ployed, as in the usualconstruction. The right hand bearing, however, is somewhat modified inorder to provide for mounting certain devices of the present inventionthereon, without interfering with the bearing performingits usualfunction and being ads justed in the usual manner. Thus, from aninspection of Fig. it will be seen that a hearing plate or disk 37 isprovided which is circular in outline and receives a bearing on a pivotscrew 38 connected to the right hand end plate 1. This bearing plate hasa central bearing opening 39 in which the platen shaft 40 is supportedin .the ordinary manner. he lower edge of the plate 37, opposite thepivot 38, is recessed to receive an eccentric 41 provided with ahexagonal head 42 by which it may be turned around a pivot screw 43. Thescrew 43 is carried by the right hand end plate 1 and also constitutes abinding screw by which the eccentric 41 may be firmly held in itsadjusted position. In accordance with the present invention I provide achamber in the periphery of the disk or plate 37 and sup- '11; portconcentrically hereinafter appear. The device 44 is apertured at 46 sothat the eccentric 41 will not interfere with the circular adjustment ofthe device 44 around the axis of theplaten'whatever may be the adjustedposition of the plate 37 and the device 44 will not interfere withthereon for any the adjustment ofthe plate 37. The device 44 carries astop 47 which I prefer to adjustably connect to said device so that thestop may receive an independent adjustment desired fraction of a linespace distance, for purposes which will presently appear. In the presentinstance, the stop projects laterally from the bodyportion or foot-piece48 of a sheet metal bracket, said foot piece being tapped to receive thethreaded stems of two headed binding screws 49. These screws pass freelythrough concentrically arranged slots 50 in the device 44, and the headsof the screws bind against the inner face of said device to firmly clampthe stop carrying bracket in theposition to which it may beadj ustedaround the axis of the platen on the device 44. A pawl 51 is mounted ona pivot screw 52 on the right handend plate 1 and has an engaging nose53 adapted toenter any of the locking notches 45 which happens to be inregister therewith. This pawl 1s pressed to its locking position .by aspring 54, and a finger piece55 on the pawl facilitates thedisengagement of the pawl from the notch 45 in which it is locked. Thepawl 51 thus locks the regulating device 44 in any of the differentpositions to which it may be rotatively adjusted," as determined by thenotch 45 in which the pawl is seated.

Fixedly though detachably mounted on the platen shaft 40 adjacent to theregulating device 44 is a disk 56 having a smooth periphery, whichfriction or roller clutch. In the presentinstance this disk isdetachably mounted on and fixed to the shaft 40 by the following means:

' A washer 57 surrounds the shaft 40 and maintains'the disk 56 andassociated parts properly separated from the regulating device. Abushing 58 which is received in a tapped opening 1n the center of thedisk, whereas the shoulder provided at the point where the reduced partof disk constitutes one member of a has a reduced threaded portion thebushing joins the 'enlargedcylindrical hub" thereof, binds firmlyagainst the outer side of the disk when the bushing is screwed home inthe tapped opening in the disk. The disk is thus firmly connected to thebushing and the latter is connectedto the platen shaft by two screws 59that extend at right angles to each other into tapped openings in thebushing, and bear at their inner ends against flattened faces 60 on theshaft. The right hand finger wheel 5' has its hub 61 connected in):

to the shaft by screws 62 in a like manner, the inner end of said hubbearing against the outer end of the bushing 58 and holding it and theparts carried thereby against outward axial movement. When the screws 59and 62 are loosened the right hand finger wheel and the bushing 58 andthe part-s carried thereby may be slipped off the shaft. Mounted to turnfreely on the bushing 58 concentrically with theaxis trolled actuatingmember or lever which in the present instance comprises two sheet metalparallel arms 63 and 64 on opposite sides of the disk 56 and free frombinding action on the sides thereof. of the arm 63 is apertured toprovide a bearing openingto receive and provide a pivotal support on theenlarged end of the bushing 58. The arm 64 has a smaller bearing openingto receive the inner reduced unthreaded end iii of the bushing 58, andthus provlde a pivotal support for the arm 64. These arms are rigidlyunited at their upper ends. As shown, a spacing washer 65 having aknurled periphery is received between armsand maintains them spacedapart. A screw bolt 66 is headed at asses through registering'openingsin a handle 68, in the arms 63 and 64 and in the washone end 67 and,

of the platen is a hand conthe upper ends of the The lower end {is er65. The threaded end of the bolt 66 coacts 1 1'3 with a nut 69 and bythese means the handle, parallel arms and intermediate washer may befirmly clampedtogether. As best shown in Fig. 8 each of the arms 63 and64 is cut out in one of the rear edges thereof, the cut-outs in botharms being identical. These cut-outs provide a recess in which a clutchroller 70 is loosely received, the roller being adapted to bear againstthe periphery of the disk 56 and being prevented from Xial displacementby two flanges 71 on the ends of the roller coacting with the outerfaces of the arms 63 and 64. The upper wall 72 of the recess in each arm63 and 6a is inclined to form a cam, both cams being identical andcoacting with the upper side of the clutch roller. The lower Wall 72 ofeach recess is ineffective on the roller. A light wire spring 73 has itsupper end seated and held firmly in a cut or slot 7 4 in the washer byclosing or partly closing the mouth of the cut. The lower free endportion of this spring bears against the front of the roller and tendsto force it rearward into clutching engagement with the inclined faces 72 and with the periphery of the disk 56. It will be understood that theforce of this spring on the clutch roller 70 may be varied bylooseningthe nut 69 and turning the knurled washer 65 until therequisite force is exerted by the spring 7 3. The nut 69 is thentightened, holding the washer in the position to which it has beenrotatively adjusted.

The cross rod 3 has connected to the right hand end thereof an outwardlyprojecting pin 75 which projects to the right from the associated endplate 1 and extends in the path of the flanges 71 on roller clutch 70 asthe latter returns rearward with its carrying lever to normal position,shown in Figs. t and 8. Such return movement of the lever and clutchroller is effected independently of the disk 56 and the platen, inasmuchas roller 70 at this time moves away from the bight or engaging positioninstead of towards it. The return movement of the parts just describedis effected by a contractile spring 76 connected at one end to a pin .77on the arm 63 and at its other end to pin .78 projecting from theassociated end plate, 1 of the carriage. The power of the spring 7 6 isgreater than that of the spring 78, so as to overcome the force of thelatter when the parts are returned to the normal Fig. 8 position. Theefiect of this is to arrest the clutch roller 70, by the pin 75, whilethe spring 76 overcomes the power of the spring 73 and continuesslightly the motion of the arms 63 and 64, releasing the wedging actionof the cams 7 2 on the roller 7 O. This frees the roller and holds itfree from clutching engagement with the periphery of the disk 56, asshown somewhat exaggerated in Fig. 8. At this time, therefore, theroller clutch mechanism is maintained released, so that the platen, andthe clutch member or disk 56 connected therewith, are adapted to beadvanced in a line space direction (as indicated by the arrow (Z in Fig.8) by the usual line space mechanism, or either of the linger wheels 5,without being interfered with by the hand actuated roller clutchmechanism.

Supported on a pivot 7 9 between the two lever arms 63 and 6 1 is alever-like locking member 80 that has an engaging toe 81 adapted tocoact with the clutch roller 70. fan outer contact edge 82 on saidlockin member extends beyond the forward edges or the arms 63 and 6%. Atthe last part of the forward throw of said arms the edge 82 is broughtinto contact with the stop 4:7 located in the path thereof. The effectof this is to slightly turn the lockin member on its pivot relatively tothe arms and force the toe 81 against the clutch roller 70. This resultsin forcing the roller with greater pressure against, or into moretenacious wedqing engagement with, the cam faces 72 and the periphery ofthe disk 56, thereby locking and holding the disk and the platenconnected therewith against overthrow beyond the position where theparts are supposed to be arrested by the stop 4:7. This of course is avariable point depending on the adjustment ofthe stop 47 in the mannerpreviously described. When the operator releases the handle 68, afterturning the platen backward the predetermined distance in accordancewith the setting of the stop 17, the spring 76 will return the handle tonormal position independenty of the platen, leaving the latter free tobe line spaced forward independently of the handle.

In the use of the machine, the parts will be set or adjusted inaccordance with the work to be done and the position of the previouslyprinted body portions of the letters, which of course will all be alikefor any given ob in hand. Referring particularly to Fig. 1 it may beassumed that the line 9 represents the first line of the body portion ofa letter previ ously printed by a multigraph machine on a letter sheet7. If it be found that the position of the initial letter W in said linedoes not exactly accord with the letter spacing machine as asheet is fedfrom between the side guides 17, but is a fraction of a letter spaceoff, then the thumb screw 86 may be turned in one direction or theother, shifting the carriage and platen until the initial letter in anyof the lines 9, 1, z and 7' written on the machine has a marginalregistration with the letter W in line 6, as indicated by thedotand-dash line 70. This adjustment may be quickly and accuratelyeffected, and when effected for one sheet remains without change for allof the previously printed letter sheets of one batch.

Let it be assumed further that the operator desires to fill in theaddress and salutation lines 9 to j inclusive in the manner indicated inFig. 1. It will be seen that these lines with the intervening spacesbetween the lines 6 and j and j and e occupy six single spaces, or adistance corresponding to six teeth of the line spacing wheel 7. Theoperator therefore releases the detent 51 and turns the stop carrier 44anti-clockwise, as the parts are seen in Fig. 4, until the last orrearward notch 45 is brought opposite the nose 53 of the detent. Thedetent is then released to engage said notch and the parts are set readyto perform the work. A previously printed work sheet f is then fedforward in the machine until the line 6 registers with the lineindicator 88, as shown in Fig. 1. The handle 68 is then pulled forwardto the limit of its movement, determined by the setting of the stop 47.This results in effecting a back-- ward rotation of the platen exactlysix line spaces, bringing the paper in position to begin writing thefirst line 9 is marginal alignment, as indicated by the line is,assuming that the carriage has been moved back to the right untilarrested by the margin stops. After this line is completed the carriageis returned to the right and line spaced in the usual manner and so onfor each of the successive lines it, 2' and jexcept that a double linespace is effected between the lines i and j, leaving also a double linespace between the last written line j and the first printed line 6 ofthe body of the letter. No further adjustment of the parts is requiredunless differently printed letter or like sheets having a differentwidth of margin are used, or a different character of spacing is desiredfor filling in the addresses. However, a socalled block heading, spacedas indicated in Fig. 1, is the character of addressing most commonlyused in this character of work, and the machine when once set requiresno further adjustment, except in special circumstances as indicatedabove. However, by the various adjustments of the devices of the presentinvention they readily lend them selves to a wide variation in use, andsuch devices are available for rapidly filling in and accuratelymatching various forms of headings and the like.

The means by which a fractional adjustment of the stop 47 on its carrier44 may be effected is, in the main, for the purpose of regulating eachclutch mechanism to give the requisite extent of backward revolution tothe platen, irrespective of the slight extent of lost motion of thehandle from normal position required to render the clutch effective.This may vary slightly in different clutches, it being difficult, as amanufacturing proposition, to make all clutchesso that they will operatewith the same deadly accuracy on all machines. Thus, for example, if oneclutch should require a lost motion of, say, one-sixteenth of an inch tobring about an engagement thereof, and another clutch should require alost motion of, say, one-thirty-sec- 0nd of an inch to engage it, theproper adjustment of the stops 47 on their carriers 44 willenable bothclutches to turn the platen backward the same indentical extent from thesame set position of both carriers 44. This independent adjustment ofthe stop 47 also will take care of any inaccuracies of manufacture ofthe carriers 44 or the cutting of the locking notches 45 therein.

The use of the spring is not essential, but T prefer to employ it inorder to enable the adjustment between the carriage and feed rack to bemore easily effected. It will be seen that the force of this spring isapplied substantially in line with the pivots 22 and 25 and tends torelieve the parts of any lateral or binding strain in the relativeadjustment between the carriage and feed rack.

From the foregoing description it will be understood that I haveprovided simple and highly effective means for attainment of the endsspecified, which means are in the nature of attachments that may bereadily embodied in existing machines, such as the No. 50 Remingtonmachine, without modifying or materially modifying, the existingstructural features thereof.
